aye, currently the game either rewards spamming so much evidence that they cannot keep up (EG blood magic) or to not make any evidence at all by only having a single cult in a large nation that you then can fully infiltrate and enshadow and thus spread said shadow everywhere without generating any additional evidence (note that cult of decadence does not make any, so you could literally go a no evidence game via going for the profitable acquisition and then going for a cult of decadence) and thus make humanity unable to create any kind of understanding by keeping hidden completely.
obv it is a prealpha rn, given it is just a way of showcasing a potential mechanic, but it will really need work in order to function the way it is intended to - because otherwise, it will create scenarios similar to the permaguarding due to a love for a character/their race or the magical arms race making lore heroes no longer care about lore tasks
